Gee bash, Ive never seen a kayak advertised as a kayak boat ?? Have you ?? just sayin you own it you call it whatever you want !! not trying to make big deal about it !!

just sayin?

I spend a great deal of time kayaking, and I do at least one multi-week international trip every year. I don't know any serious kayaker who doesn't call his/her boat a "boat."

You want advertisements? Both my boats are Eddylines, so I jumped on their website to see what whether people are using the term "boat" to apply to their boats. Guess what? Almost every kayak owner who is quoted in the ads uses that terminology.

They're all boats.
Viz: I have a small boat which I keep on the deck of my big boat. My neighbour has a bigger boat than me. There are much bigger boats than that. Take the USS Enterprise as an example.
Now that's a f****n' big boat!
